Abstract

"We present a dispersion compensating fiber Raman amplifier for the L-band, obtained by pumping a dispersion compensating fiber with a high power 1480 nm Raman pump. The device described here is useful for the upgrade of DWDM transmission systems, considering that increasing the transmission bit rate requires extra power budget and dispersion compensation. The dispersion compensating Raman amplifier was tested in two configurations, backward and forward pumping. A net gain of 13 dB is obtained at 1580 nm for 600 mW of 1480 nm backward pump power. The on-off gain in this condition is 27 dB."
